Wiring the InSight GPS 50-W to the DB-9 Connector
GPS software interface protocol is based on the National Marine Electronics
Association (NMEA) NMEA 0183 ASCII interface specification Version 2.0.
TIP:
This step requires a soldering iron and solder.
1.
Solder the Brown TX wire directly to Pin 2
.
2.
Solder the Green RX wire to Pin 3.
3.
Splice the Black wire. Solder ½ of the spliced Black wire to Pin 5 and the other ½
to a common ground on your electronics panel.
4.
Connect the Red wire directly to your 12 or 24VDC electronics panel with a 1A
fuse, either in line or on the panel.
5.
Check your solder connections carefully to verify that all wires are connected to
the proper pin numbers and that no solder is touching any other pin.
